anglais. The condensation reaction of benzaldehyde with nitromethane that resulted in the formation of β-nitrostyrene was studied in ionic liquid media — (2-hydroxyethyl)ammonium carboxylates (formates, lactates, acetates) without application of any other catalyst. The dependence of product yield on the ionic liquid cation and anion structure, the polarity of the ionic liquid and the pseudo-pH value of the reaction medium was investigated. The highest yield of the condensation reaction product — β-nitrostyrene was achieved in (2-hydroxyethyl) ammonium formate medium.

Pētīta β-nitrostirola sintēze benzaldehīda kondensācijas reakcijā ar nitrometānu jonu šķidrumu (2-hidroksietil) amonija karboksilātu (formiātu, laktātu, acetātu) vidēs bez citu katalizatoru lietošanas. Pētīta reakcijas produkta iznākuma atkarība no jonu šķidrumu katjona un anjona uzbūves, jonu šķidrumu kopējās polaritātes un reakcijas vides pseido-pH vērtības. Visaugstāko β- nitrostirola iznākumu nodrošināja (2-hidroksietil) amonija formiāta lietošana par reakcijas vidi.
